TREATMENT TABLE.

Application filed September 14, 1922. Serial No. 588 267.

vide a device of the type referred to wherein the attending physician may employ mechanical means to treat a patient, to locally and selectively increase the blood supply and nourishment of the tissues, which means maybe permitted to function for relatively long periods of time, without his continued and immediate presence, wherefore he can devote his time and efforts to other patients.

Another object of my invention is to provide a device for the purposes stated, which is capable of adjustment to attain various degrees and kinds of relative movement of the table parts, by mechanical means, whereby the same device may be employed to treat various patients in various ways.

Another object is to provide a simple and efficient device for the purposes stated, and adapted to be readily connected to and disconnected from the table, providing for selectively operating the table manually or by power.

Another object is to provide a device for the purposes stated having a minimum of parts, thereby reducing the wear on the device and rendering the device of such nature that persons of little or no mechanical skill may readily manipulate and adjust the device without danger to apatient or himself, and Without likelihood of damage to the device.

The table disclosed herein, is similar to that shown in my referred to patent and comprises a base 6 on which is mounted a vertically adjustable standard 7 supporting a frame 8 on which is mounted a main top or table pad or section 9. The frame 8 carries a recessed sleeve 10 in which is rotatably con tained a vertical shaft 11, carrying at its upper end a yoke like head 12, the arms 13 of which rotatably support a horizontal shaft 14. V

The shaft 14, the side bars 15, and the cross brackets 16, 160' and 17 constitute an auxiliary frame extending outwardly from the shaft 14 and pivotally mounted by means of the shaft 14 upon the arms 13 of the head 12. A shaft 26 is journaled in bearings in v the cross brackets 16 and 160 so as to form a hinge axle on which the table top'section 25 is adjustable. endwise and also oscillatable about said hinge axle as a center. The hinge axle 26 is clamped rigidly to the brackets 29 and 30 which brackets are attached to the under faceof the table top section 25; A screw rod 26 is in alignment with the hinge axle 26' and is supported rotatably at opposite ends in brackets 28 and 29 which are attached rigidly to the under face of the top section 25. The screw rod 26 is rotatable by means of a hand crank 27, and is threaded through a recess in the end plate 17 to enable the top section 25 to be adjusted endwise on the side bars 15 by rotating the screw rod 26.

The cross bracket 16 is movable endwise on the rods 15 but is held by a set screw traveling in a groove in shaft 26, or similar means against movement endwise of the shaft 26. 7 cars 70, and opposite said projections 70 are metal shoes 71 attached to opposite sides of the under face of the top section 25. A sleeve 7 2 is adjustable endwise of shaft 26 by means of a hand lever 7 3 pivotally attached to the under face of the top section Bracket 16 carries projecting 25 and engaging said sleeve 72 to move it endwiseon shaft 26. The sleeve 72 is provided with lateral projections 74 adapted to be interposed between the shoes Hand the projections 70 to prevent oscillation of the top section 25 relative to the rods with the shaft 26 as a hinge axle. When the sleeve 72 and projections 74 are retracted from on gagement with members 70 and 71, the top section 25 free to oscillate upon the hinge axle 26 andthe top section may be directly attacl'ied to the power driven members to oscillate the top section 25 relative to the rods 15 upon the hinge axle 26 while the rods 15 remain locked against oscillation in vertical plane upon the axle 14, and irrespective of Whether the top section 25 is being-oscillated in a horizontal plane upon the axle 11. A yoke shaped locking member 76 provided with a handle 7 7 is pivotally mounted upon the .axle 14 and is provided with projections 8 in position to engage the curved faces of projections 79 carried at opposite'sides ofthe frames to enable the head 12 and arms 15 to be rigidly locked to the frame '8- against oscillation upon the axle -11 when desired, and to be free to oscillate upon the axlell when the projections 3 and 79am out of engagement. The table top section 9 may be adjustable or not as may be desired.

At the lower end of the axle 11 is a collar 18 rigidly mounted thereon. Pivotaliy attached to the collar 18 are parallel bars 19 which constitute guide ways along which .a carriage 20 is adjustable by means of a screw rod operable through the hand crank 21. A spring 22 is attached at its upper end to the axle 14, and at its lower end to the carriage20, so that adjustment of the can riage 20 along the ways 19 will increase or decrease the available tension of the spring '22 tending to lift the ways '19. An adjustable telescopic thrust bar comprising a tubular member 24 pivotally attached to the ways 19 and a threaded rod 24 pivotally attached to a cross bar connecting the two rods 15 and telescoping into the member 24 and pro vided with an adjusting nut 24 to engage and restupon the end of the member 24 provides for transmitting the upward thrust or tension of the spring 22 through the ways I 19, and'members 24, 24 and 24 to the rods 15 and top-section 25, and enables the tension supporting the top section 25 to be adjusted to substantially counter-balance the weight of the particular patient being treated. A latch bar 8 is adjustable endwise along the pedestal 8 to engage the head 12 and lock the head 12 and shaft 10 against oscillation relative to pedestal 8.

The end plate 17 has a yoke like lower extension, whereby downwardly extending spaced arms 31 and 32 are provided. The a r1n31 carries a slide block 33 which is connected with the arm by a universal joint 34. The slide block extends between and engages the branches 35 and 36 of the p1votally mounted upper portion 37 of an oscillatory drive lever, the lower end 33 of which lever is pivotally mounted at 391 on the housing The lower lever portion 38 has an elongated slot 40 extending longitudinally thereof and a sliding drive block 41, carried by the crank arm 42 is reciprocally movable said. slot. The crank arm 42 has a'radial slot '43 in which. is adj ustably mounted a stud sha t 44 rotata'bly engaging the drive block 41. Any suitable means for rendering the stud snaft 44 radially adjustable in the slot43 may be employed, for exampl head 45 on the one end of shaft 44and a nut 46 on the shaft intermediate the ends of the shaft may be employed as shown in Fig. 4 to lock or clamp the siaft in its adjusted position. From the foregoing it will be readily apparent that the distance at which the stud shaft is fixed in relation to the axis of the driven shaft 47 will predetermine the limits of movement-of the oscillating lever, therefore pie-determining the limits of horizontal reciprocation of the auxiliary table 25 about the vertical shaft or axle 11.

The driven shaft 47 is revolubly mounted on the housing 39 and carries intermediate its ends a worm wheel 48 engaging a worm 49 driven by th drive shaft of the motor 50. The housing has formed within it a suitable oil chamber 51 in which the worm and worm wheel are contained.

The crank 42 is mounted on one end of the shaft 4?.

A second crank 52. is mounted on the other .radial slot 53 and has adjustably mounted on it a stud shaft 54 on one end of which is pivotally and revolubly mounted the lower arm 55 of a turn buckle, the upper arm 56 of which turn buckle is pivotally connected with the arm 32 of the end plate 17 by means of an universal joint 57. The tubular body 58 of the turn buckle may be rotated in relat-ion to the turn buckle arms to raise or lower the center of vertical oscillation of the auxiliary table pad 25' about the horizontal shaft 14. A suitable locknut 59, mounted on the turn buckle, retains the turn buckle parts in their adjusted relation. The stud shaft 54 may be locked at various adjusted positions in the radial slot 53 by any suitable means such as described for securing the stud shaft 44 on the crank 42. The stud shaft 54 may carry a suitable collar 60, revolubly mounted on, said shaft and having radially extending pins 61 and 62 on which the branches 63 and 64 of the forked end'of the turn buckle arm 55 are pivotally mounted. From the foregoing it is readily apparent that the adjustment of the stud lll) ill

shaft radially of the crank 52 will determine the limits of vertical reciprocation of the auxiliary table top 25. i

The connecting member 38' reciprocates in one plane- The connecting member 37 is pivotally connected to member 38 by a pin 120, and has a tongue 121 seated in a corresponding slot 122 to resist the strain of oscillating the top section 25. The member 37 is designed to move relative to member 38 so as to oscillate in relatively different planes depending upon the movements of the top section 25 vertically.

In Fig. 8 I have illustrated one of the universal joints preferably employed to connect the upper ends of the members 37 and 56 to the members 31 and 32, and also to connect the member 55 to the crank arm and as shown in Fig. 6 to connect the member 55 to the crank arm 52 and to connect the member 56 to the top section 25. Said universal 'oints each comprise a yoke 124 having a t readed shank 125 by means of which it may be bolted in place. A block 126 is pivotally mounted relative to yoke 124 by means of screws 127 and 128, provided with conical points and held in place by lock nuts 129, The block 126 is provided with a recess to receive the pin 130 and journal thereon. Opposite ends of the pin 130 are supported in recesses in opposite ends of a yoke shaped member, for instance member 55 or 56. The pin 130 may be held against displacement by a cotter pin 131. and the driving mechanism may be connected or disc-onnected from the top section 25 or partly disconnected by removing one or more pins 130. In Figs. 9 and 10 I have illustrated one type of means whereby the relative movements and adjustments of the driving crank arms may be varied as required. Thus the lead of one crank arm, for instance crank arm 52 over the other crank arm 42 may be attained by loosening the set screw 52 and adjusting the crank arm 52 relative to its shaft 47.

The end of shaft 47 which drives the crank arm 42 is preferably provided with a pinion 107 which meshes with an internal gear 110 to drive the crank arm42 when desired at a relatively slower rate of speed than that of the shaft 47, and so as to automaticallv and periodically change the rela tive positions of the crank arms 42 and 52, and consequently the path traveled by the top section 25 as the joint result of its vertical and horizontal movements. The hub 108 of the crank arm 42 is journaled in a journal box 109 carried by the housing 39. l/Vhen it is desired to drive the crank arm 42 at the same rate of speed as that of the shaft 47 to preserve one driving relation of the crank arms 42 and 52, I preferably employ a detachable connecting member 114 which is seated over a polygonal shank 112 carried at the end of the shaft 47 to cause member 114 to rotate With and at the same speed as shaft 47. A screw or bolt 115 passing through a radial slot in the member 114 and threaded into the crank arm 42 causes the crank arm 42' to be driven at the same speed as the shaft47 through said member 114 and screw 115,- thus providing for readily detaching the member 114 when desired, and for selectively driving the crank arm 42 at the same speed as that of shaft 47 or at a somewhat slower rate of speed. When the slower speed for crank arm 42 is employed the relative positions of the crank arms 42 and 52 are continuously and automatically changed and the path of movement described by the top section 25 automatically changes to thereby provide changeable exercise for the patientcalculated to force a blood supply and nutrition more effectively to points where required. As illustrated in Fig. 1 the pitman 56 is shown connected to the arm 32 of plate 17 to reciprocate the top section 25 through a pre-determined range of movement in a vertical plane about the horizontal axle 14 while the members 37 and 38 may be employed at the same time to oscillate the top section 25 in a horizontal direction whereby the top section '25 Will describe a path of movement resulting from the compounding of said vertical and said horizontal movements. Either of said movements may be employed independently by (liSCOIlIlGCtlIlg the other driving member from the table top.

As illustrated in Fig. 6 the pitman members 55 and 56 instead of being connected from the crank arm 52 to member 32 are shown connected from the crank arm- 52 to a universal joint connection 140 at one side of the table, so as to cause the table top section 25 to be oscillated upon its axle 26 from the crank arm 52 instead of being oscillated in a vertical plane from crank arm 52 as shown in Fig. 1.

As illustrated in Fig. 7 the universal joint connection 140 is connected by means of a turn buckle member 141 to an car 142 projecting from the casing 39 by means of a hinge bolt 143, while the pitman members 55 and 56 are connected from the crank arm 52 to the member 32 as shown in Fig. 1, to thereby provide for simultaneously oscillating the top section upon its axle 26, upon its axle 14, and upon its axle 11. Means is provided to independently lock the top section 25 against oscillation uponits axle 26', upon its axle 14, and upon its axle 11, hence by locking the top section 25 against oscillation upon one or two of said axles motor power may be employed to oscillate the top section 25 upon one axle only or upon two axles only at a time. Also if desired all the motor connections with the top section 25 may be readily released and the top section Ill 25 manually actuated, "or the top section 25 may be actuated partly byymotor and partly by manual energy.

It will be noted that by employing either of said motor drive connections separately or by their joint use, many different movements and compound movements may be given to the auxiliary top section 25, and that by reversing the motor the direction of these. movements may be changed.
